' CULVERT.

Application led January 3, 1924. Serial No. 684,138.

The invention relates to improvements in sheetnietal culverts" of the sectional, nest-v lable, or knock-down type.

Such culverts are colnmonly formed of half round sect-ions` corrugated transversely, and terminating at their sides in connecting flanges provided with corrugations conforming` to the arch corrugation of the body portion of the .section.

In assembling culverts of this type, when it is desired to form a square end,vdiffe'ren tial sections must begemployed, one of which terminates in a flared end and the other of which terminates in a contracted end. g Such a construction is illustrated in my prior Patent No. 882,081 of March 17, 1908, and requires the manufacturer to make differential sections which makes it necessary for the dealer to keep the same in stock.

This not onlyincreases the cost of manufacturing but requires considerable care in filling an order to insure that theproper kind of sections are included, in order to terminate a culvert with a square end without an excessive amount of overlapping sections at the end joints.

The object of the present invention is to provide a corrugated sectional culvert which will overcomelthese difliculties, and is at* tained by.- forming the culvert yof interchangeable sections wherein the flange on one s1de is provided with corrugations which are concaved in conformity with the arch corrugations while the flange on the other side is provided with corrugations which are concaved reversely with respectto the archy corrugations, whereby when one section is laid upon the other, in assembling the lculvert, the flange corrugations will register and nest one within the other, while the ends of the sections are alike.

The invention is illustrated in the accompanying drawings, being part hereof, in

. Fig. 4, a fragmentary perspective view ofportions of two sections showing the s'ame in position to be assembled;

Fig. 5, a side elevation of a portion of a culvert embodying the invention; and

4means may be Fig. 6, an end elevation of several of the culvert sections nested.

Similar numerals of reference refer to corresponding parts throughout the drawings.

lhe culvert sections indicated at 1 are each of the same kind or type and may be of any suitable length. Each section is semi-cylindrical and is preferably corrugated transversely with the arch corrugations 2, and it is essential that each end of the section be alike, the sections preferably terminating in the flared ends 3 as illustrated.

Each section is provided along its side edges with the angular attaching flanges 4 and 5, the `flange 4 being provided with corrugatlons 6, conforming to the arch corrugations 2, in the body portion of the section, while the flange 5 is provided with corrugations 7 concaved reversely with respect to the arch corrugations. f

Thus, when two sections are assembled, as shown in Fig. 2, the corrugated atta/ching flanges will register an-d nest, and a square end will be provided at each end of the culvert. Bolts 8 Aor other suitable fastening provided for connecting the flanges together.

As shown in Fig. 5, when it is desired to stagger the joints throughout the length of the culvert, the same may be built up of full length sectlons 1, and half length sections 1", formed as above described, only a single type of section being required.

' Sections of this typemay be easily nested together as shown in Fig. 3, as the corrugated flanges 4 upon the one side and the corrugated flanges 5 upon the other side of each section reg1ster and nest together in the same manner as the arch corrugations 2 through the body-portions of the sections.

By the described leonstruction and arrangement of the improved form of culvert sections it is only necessary for the manufacturer to make, and the dealer to keep in stock, one type or kind of sections, thus reducing the manufacturing cost and obviating the possibility of including the wrong type of sections in filling an order; making it possible to terminate a built up culvert with square ends, without the necessity of using differential sections and without an excessive/'amount of overlapping of sections sections all of one length, placed together in the manner shown in ig. 2, the ends of adjacent pairs of sections being lapped and bolted together.

I claim: 1. A culvert section having lateral flanges with transverse corrugat1ons reversely formed on opposite side edges.

2. A culvert section provided With trans- Versely corrugated flanges at its side edges, the corrugations in one flange being formed reversely with respect to thecorrugations in the other flange. f

3. A corrugated culvert section terminated alike at both ends and having transversely corrugated flanges at its side edges, the corrugations on one flange being formed reversely with respect to the corrugations upon the other flange. v

4. A corrugated culvert section having corrugated flanges at its side edges, the corrugat1ons in one flange being formed the same as the corrugations in the body of the section, and the corrugations in the other flange being formed reversely with respect thereto.

5. A' corrugated culvert section terminated alike at both ends and having corrugated flanges at its side edges, the corrugat-ions in one flange being formed the same as the corrugations in the body of the section and the corrugations in the other flange being formed reversely to the corrugations in the body of the section. e

6. A culvert composed of corrugated sections, all of which are alike, each section terminating in flared ends and having transversely corrugated flanges at its side edges, the corrugations upon each `flange being formed reversely with respect to the corrugations in the other flange.

7 A culvert composed of sections, all of which are alike, each section having transversely and reversell;7 corrugated flanges upon opposite side edges.
